[REGRESSION] `TextEdit::min_size` no longer honors `min_size.y`

[AmmarAbouZor]

Describe the bug
After upgrading from egui 0.33 to 0.34, TextEdit::singleline(...).min_size(vec2(_, height)) no longer respects the requested minimum height.

The same code worked in 0.33. In 0.34, width still behaves as expected, but the height falls back to the widget's internal single-line height.

Expected behavior
The TextEdit should honor min_size.y, the same way it did in egui 0.33, so the widget can match the row height.

Desktop (please complete the following information):

• OS: Linux Ubuntu 24.04 LTS on Wayland
• Version 0.34.1

Workarounds

• ui.add_sized(...) can force the outer slot size, but it does not fully replace the old behavior because the inner text layout still uses the widget's natural height.
• Adjusting TextEdit::margin(...) can partially work around this, but it feels like a workaround for missing min_size.y handling rather than the intended API.
